Cisco network holes


Cisco network holes

Antony Savvas

Cisco has been forced to issue two security patches to block holes in its Internetwork Operating System (IOS).

One of the flaws leaves IOS-based Cisco devices open to a Denial of Service (DoS) attack, and the other one allows intruders unauthorised access to a network.

The DoS vulnerability affects routers and other devices running Secure Shell (SSH) servers for remote management. The hole affects IOS-based devices running SSH version 2.

The vulnerability which allows intruders into a network can allow an attacker to send rogue code to a router to allow access.

This hole only affects devices running IOS Easy VPN Server.
